I had a question regarding the AP test - anyone who knows please answer. I answered a section of a problem regarding a Vector (asking for direction and magnitude), and my answer was as follows: 802.5N @ -333.5 degrees The answer was 802.5N @ 26.5 degrees Any physics teacher should know that -333.5 = 26.5... Anyways, I got it wrong, however no where in the directions did it state that I needed to use a positive angle. Others got it correct for simply putting 802.5N @ 26.5 degrees..nothing more. His logic for taking the points off was because I didn't say "-333.5 degrees above the horizontal" Would I have gotten this wrong on the AP test? If not i'm going to have a talk with him, because i suspect he's being a jerk.
